[firebase-messaging] Token change callback is not triggered in android

[CatchABus]

It seems that onToken callback is never called. I reinstalled app and deleted token but none of these seem to trigger it.

Sample:

var messaging = firebase().messaging();
// This is never called
messaging.onToken(function(token) {
  console.log(token);
});
messaging.showNotificationsWhenInForeground = true;

try {
  await messaging.deleteToken();
  let token = await messaging.getToken();
} catch(err) {
}

In order to confirm this, I also created my custom Service class and assigned it as a service into my app's manifest file.
The following class method was triggered on app start and token deletion.

package org.dnr;

public class FirebaseMessagingCustom extends com.google.firebase.messaging.FirebaseMessagingService {
	@Override
	public void onNewToken(String token) {
		System.err.println("Token: " + token);
		super.onNewToken(token);
	}
}

I wonder if the following service declaration is really working: https://github.com/NativeScript/firebase/blob/main/packages/firebase-messaging/src-native/android/messaging/src/main/AndroidManifest.xml#L10
